@jise - You are using a very old version of rtMedia. There is no templating system in that for you to override the ajax pagination.
Please update from – http://wordpress.org/plugins/buddypress-media/
Once you have updated to the latest version, you could make changes to the
album-gallery.php and put your markup with a different class to stop the ajax pagination.
Refer to this link for more details on how to override templates in rtMedia -> http://rtcamp.com/rtmedia/docs/developer/templating-system/
